Following Georges St. Pierre's win over Jon Fitch last night, the UFC wasted no time hyping the champion's next opponent -- lightweight title holder BJ Penn.

Touted as a battle of champions, the UFC has bona fide superfight on their hands. One that could even happen on Canadian soil -- company president Dana White made it clear that he hopes to hold another event in Montreal before the year's end.

But has Penn done enough to jump up a weight class and earn a fight with St. Pierre?

There seems to be a lot of fighters talking about competing in more than one division these days. Anderson Silva recently made his light-heavyweight debut, knocking out James Irvin in little time. However, this move was more out necessity as the Brazilian powerhouse has completely run roughshod over the middleweight division.

While both St. Pierre and Penn have talked about moving up in weight class, neither man has been quite as dominant as Silva. They also still have some credible opponents left.

Penn in particular has only fought three times since returning to lightweight -- arguably the most stacked division in the UFC. He's won each match in impressive fashion, but before that he was 0-2 at welterweight, with one of those loses coming to St. Pierre via a very close split-decision.

Despite this, the UFC should make the rematch happen.

Both fighters have come a long way since their first encounter. St. Pierre went through a rocky period following his loss to Matt Serra, but has since returned to perform better than ever. Penn, on the other hand, has finally begun taking his training seriously. With a solid gas tank behind him, he's as dangerous an opponent as they come.

The last time they crossed paths Penn took the fight to St. Pierre and absolutely punished him during the first round. The Montreal native came charging back to take the next two, but if Penn hadn't gassed, he may very well have won. Hell, some fans still argue that he did win.

Regardless of which side of the fence you fall on for that fight, you can't call yourself an MMA fan if you're not looking forward to a rematch.

The only downside to all this is Kenny Florian will have to wait even longer for another shot at the lightweight title.

JON FITCH IS A TRUE WARRIOR

There is simply no quit in him. He was in trouble on more than one occasion last night, but always managed to regain his composure and charge back. He even got a few good shots off in the process.

If you didn't respect him before, you should now. He put up a hell of a fight, but was simply outclassed.

BROCK LESNAR HAS ARRIVED

Lesnar looked like an animal against Heath Herring. For 15 minutes he controlled every aspect of the fight. When it was all said and done, the Texas Crazy Horse looked like he had been run over by an 18-wheeler.

Lesnar still has a lot more work to do -- he definitely needs to learn how to break through his opponents ground defense and rely less on positional control -- but if he can keep his head in the game, he has all the potential to be UFC heavyweight champion one day.
